Wifi pentesting basics skills assessment final question

Connect to the WiFi network and submit the flag found at IP 192.168.1.1 or 192.168.2.1.

i have found the password and the ssid asked in the first two questions but i am unable to connect to the network in the third question, i have tried all the 3 methods in the connecting to wifi section of the module and am still unsuccessful. The wifi network had wpa2 encryption enabled according to airodump-ng. Can you please point me in the right direction with respect to connecting to the wifi?
